la présence simultanée de rouille verte 2 et de bactéries sulfato-réductrices en corrosion perforante de palplanches en zone portuaire

Mossbauer spectroscopy reveals that the corrosion of steel sheets in a harbour area in the presence of sulphate reducing bacteria is accompanied by green rust 2, a ferrous-ferric sulphated compound of definite composition, 4Fe(OH) 2 , 2FeOOH, FeSO 4 , nH 2 O, mixed with magnetite
